I want to implement an HTML5 file picker <input type="file" ...>
which accepts all kinds of files.
But it should let the user select image/*
and video/*
files.
To be more precise: I'm trying to disallow images and videos. Anything else should be allowed.
The only way I currently see is to define a set of accepted file extensions (and/or mime types), but I don't think it's feasible to add a list of hundreds of mime types just to prevent that the user can select image and video files. So that wouldn't be a satisfying solution.
I'd prefer a JavaScript free solution, if possible.
